Default New stock turbo dyno record, 4/25/13 - 04-25-2013, 01:05 PM

Hey guys,

Had a chance to get our E92 manual back to the dyno today. We've recently replaced the clutch and added a meth kit.

Full mod listing:

JB4 G5 ISO
BMS back end flash -- "race" file
BMS *********
CPE intercooler
CPE chargepipe w/ tial valve
BMS DCI
BMS OCC
Spec clutch w/ steel single mass flywheel
BMS 2.2g meth kit w/ 80% ethanol / 20% water, CM12 nozzle
E40 fuel (40% E98, 60% pump 91 octane)
"Option2" inline booster pump

I'll post the log later but peak boost was ~20.5psi and we're running around 13 degrees peak advance on it. Overall car performed very well and we were happy to raise the bar on stock turbo performance a bit.

Attached is the dyno sheet and a photo of the car & Jon working the dyno software.

is the inline pump necessary? Or was it just added for the headroom? I am concidering it but havent decided yet. I normally run 93 but would love to do a 50/50 e85 fill sometimes.

We used to run the car on E50 only and the pump was needed. But for a meth setup most likely isn't required. The car has a 3.5 bar map sensor and we're basically running map 3 w/ a 85 additive. Not for the faint of heart but makes for a fun dyno day.

You're just trying to break the fans so you have a legit reason to strap stage 3's on and get some fancy numbers with less parasitic loss than the slushbox, admit it! Sneaky sneaky breaking some records on the way lol. Nice looking wheels btw.

Wow...Crazy...so how does 21psi on stock turbos compare to 21psi on RBs?

Added the 461rw log to the first post. Looks like boost was 1/2psi less than I thought. Was just going by gauge in car as we did the runs.

This boost curve on RBs would be worth ~50rw more all else being equal. And the RBs would hold that much better at higher RPM.

With a similar advance curve and similar peak boost with RB turbos, we've done 520rw.

Afr looking great on that dyno, I would like to see this or even better with 100% e85, there is someone experimenting with the fuel rail in another post, I was running full e85 but went back to 50% cuz of misfires. Also with 100% e85 my clutch was slipping badly, probably making a lot more torque....

The N54 never ceases to amaze me! Great job Terry.

It would be cool to see those comparisons overlaid, anyone capable of doing that?

Not sure, I'd have to overlay your logs to see. But on the RBs we've never gotten overly greedy with low end boost as they just burn up those ATs anyway.

Sure, here is a dyno from sranch335's RB turbos. MT with same mods basically. How does ~100rw at higher RPM sound?

Just out of curiosity, you got those numbers with stock exhaust? Stock midpipes? Do you think you could see a few more whp with out those cats and maybe a further single digit increase from exhaust?

Awesome.

Dang...that really demonstrates how quickly us stockers run out of steam. That increasing HP delta from 5k to 6.5k hurts!

I run a 80-85 daily. Noticed you used a CM12 nozzle....do you prefer this to the the CM14...would you use a CM12 on a RB powered car also? Just curious.

Do you really mean 80% Ethanol / 20% water? Or did you mean 80% Methanol? Just trying to see if your spraying meth or ethanol.

We use ethanol in the meth tank. E98 to be exact. Normally straight, but we had a bit of water in there from installing the kit / testing for leaks. I prefer ethanol because it's not as toxic and is almost the same octane level. It's also easier for us to obtain as we keep 55 gallon drums at the office.
